For ground cover in shade you should try geranium macrorhizum which has scented leaves which turn red in winter and then produces fresh leaves and pale or deep pink flowers in spring, depending on variety.
Geranium Kashmir white is another goody and you can try the variegated form of ground elder which lightens up a dark spot but has softer foliage and stems and is not invasive like its weed cousin. Easy to control especally if you remove the flowers - Aegopodium podagraria variegatum.
Epimediums do well in shade too if you can provide plenty of well rotted organic matter to enrich the soil - garden compost or manure will do.
